Ati 4890 vs 9800gx2 1gb (2gpu) nvidia

OUT OF 2 WHICH HAS GREATER PERFORMANCE?

Performance wise, any game that allows sli that is, the 9800 gx2 will beat it for sure. But the 4890 comes close, i would rather get a 4890 myself.

The 9800GX2 would have a little more performance than the 4890, but only if it were an SLI optimized game. Even at that, the 4890 is an excellent overclocker, and I'd rather have a single GPU. The 9800GX2 was a joke of card, seeing as two 8800GTs outperformed it, and at the time when it was $600, you could put two 9800GTXs in SLI for exact same price.

Yes and the 9800GTX in TRI-SLI was faster then 9800GX2 in QUAD SLI it is like how the GTX 285 in TRI-SLI are faster then GTX 295 QUAD SLI.
